Google Cloud Certified - Professional Cloud Network Engineer Questions and Answers

Question 1

You need to configure a Google Kubernetes Engine (GKE) cluster. The initial deployment should have 5 nodes with the potential to scale to 10 nodes. The maximum number of Pods per node is 8. The number of services could grow from 100 to up to 1024. How should you design the IP schema to optimally meet this requirement?

Options:

A.

Configure a /28 primary IP address range for the node IP addresses. Configure a (25 secondary IP range for the Pods. Configure a /22 secondary IP range for the Services.

B.

Configure a /28 primary IP address range for the node IP addresses. Configure a /25 secondary IP range for the Pods. Configure a /21 secondary IP range for the Services.

C.

Configure a /28 primary IP address range for the node IP addresses. Configure a /28 secondary IP range for the Pods. Configure a /21 secondary IP range for the Services.

D.

Configure a /28 primary IP address range for the node IP addresses. Configure a /24 secondary IP range for the Pads. Configure a /22 secondary IP range for the Services.

Question 2

Your company’s on-premises network is connected to a VPC using a Cloud VPN tunnel. You have a static route of 0.0.0.0/0 with the VPN tunnel as its next hop defined in the VPC. All internet bound traffic currently passes through the on-premises network. You configured Cloud NAT to translate the primary IP addresses of Compute Engine instances in one region. Traffic from those instances will now reach the internet directly from their VPC and not from the on-premises network. Traffic from the virtual machines (VMs) is not translating addresses as expected. What should you do?

Options:

A.

Lower the TCP Established Connection Idle Timeout for the NAT gateway.

B.

Add firewall rules that allow ingress and egress of the external NAT IP address, have a target tag that is on the Compute Engine instances, and have a priority value higher than the priority value of the default route to the VPN gateway.

C.

Add a default static route to the VPC with the default internet gateway as the next hop, the network tag associated with the Compute Engine instances, and a higher priority than the priority of the default route to the VPN tunnel.

D.

Increase the default min-ports-per-vm setting for the Cloud NAT gateway.

Question 3

You are designing a new global application using Compute Engine instances that will be exposed by a global HTTP(S) load balancer. You need to secure your application from distributed denial-of-service and application layer (layer 7) attacks. What should you do?

Options:

A.

Configure VPC Service Controls and create a secure perimeter. Define fine-grained perimeter controls and enforce that security posture across your Google Cloud services and projects.

B.

Configure a Google Cloud Armor security policy in your project, and attach it to the backend service to secure the application.

C.

Configure VPC firewall rules to protect the Compute Engine instances against distributed denial-of-service attacks.

D.

Configure hierarchical firewall rules for the global HTTP(S) load balancer public IP address at the organization level.
